Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.

What are the geologic periods named from?
Most geologic periods are named for the location where rock formations were first found that contained fossils from that period, some others (e.g. Carboniferous) were named for materials associated with the fossils.
What is the during which geologic period did all three fossils form?
To accurately answer your question, I would need to know which specific fossils you are referring to, as different fossils can originate from various geologic periods. If you provide the names of the fossils or their characteristics, I can help identify the geologic period during which they formed.
What do the colors on a geologic map represent?
Geologic maps use color to represent various types of geologic features or units (a particular type of rock with a known age range).
Where do the names of the periods come from on the geologic time scale?
The names of the periods on the geologic time scale are derived from various sources, primarily reflecting geographic locations, significant fossil discoveries, or notable geological events. For instance, the Cambrian period is named after the Latin name for Wales (Cambria), where rocks from this time were first studied. Other periods, like the Jurassic, take their names from specific regions (like the Jura Mountains) where key rock formations were identified. Overall, these names help convey the historical and geological significance of the times they represent.
Earth geologic time interval from oldest to youngest?
The Earth’s geologic time scale is divided into several hierarchical categories: eons, eras, periods, epochs, and ages. The oldest eon is the Hadean, followed by the Archean, Proterozoic, and Phanerozoic, which is the current eon. The Phanerozoic is further divided into three eras: Paleozoic, Mesozoic, and Cenozoic, with the Cenozoic being the youngest. Within these divisions, geological time is further refined into various periods and epochs to represent significant events in Earth's history.
What is a person who digs up dinosuar bones called?
A person who digs up dinosaur bones is called a paleontologist. Paleontologists specialize in the study of prehistoric life through the examination of fossils, including dinosaur bones. They use various techniques such as excavation, analysis, and interpretation of fossils to understand the history of life on Earth.
How are geologic units of similar ages shown on a geologic map?
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
What do colors represent on a geological map?
Geologic maps use color to represent various types of geologic features or units (a particular type of rock with a known age range).
